And, with #kneething garnering over 85 million hits on the app, it does make you curious about what all the hype is about.

What Is The Knee Thing?

So, what is the knee thing? You're not alone in asking: Plenty of folks are wondering just what is the knee thing on TikTok.

The viral TikTok move is a foreplay technique that can get vulva-havers turned on and ready for more—or you know, can just make the makeout even hotter.

Rather than using your hand to touch a person's vulva, the knee thing requires you to put your knee between your partner's legs instead, applying very gentle pressure and movement. This can be an incredibly sensual, spicy way to get things going. This move is also exceptional because it doesn't need to lead to further sexual contact and can be just as good on its own. It can be a great way to explore what you're into, what feels good for you or your partner, how to feel your best sexually and more.

Now, it's important to remember that regardless of gender or sexuality, anyone can try out the knee thing—if it feels good for you and your partner. Whether you're queer, trans, in a cishet relationship or you're hooking up with the hottie that lives next door, this sexy trend works if it works for you and your body.

How to Do The Knee Thing

If you're looking to actually try the technique out, TikTok is filled with advice: "For all you people who don't know what the knee thing is," TikTok user @thatbishdeanna explains. "It's when you're making out with someone [and] it doesn't matter what gender is doing it, and one person's legs are spread out and the other person puts their knee in between their legs."

When it comes to practicing this move, the key is to apply gentle pressure and movement. If it's not gentle, it could actually hurt the person or feel like too much friction. As with a lot of things, slow and steady wins the race.

Another good thing about trying this move is that you don't have to be in one specific position to try it out. As it offers variations, you could be on top of the other person, side by side or even standing.

Another TikTok user, @adrianxortiz, explains how you might use it in your next makeout session: "When you guys are laying down, you're making out and stuff, you're both on your sides, they're going to take their knee and apply gentle pressure to that one area."

So, when you're having a sexy time with your partner, consider making it a bit hotter with this trendy, sensual move.

What Folks Have to Say About The Knee Thing

The reviews are officially in. TikTok users such as @jimecorteso have been using the social media app to rave about the move. Here's what other TikTok users have to say about the knee thing:
